Dark Object Palettes

Dark palettes exist for all but two of the enemies and minibosses. Plasma Wisp and Magical Sweeper don't have them due to their constantly cycling palettes. These palettes would be used in dark rooms. As it is, there are only 2 dark rooms in the game, only 6 different kinds of enemies inhabit them, and no minibosses lurk there.

To enable the dark object effect in Green Greens' first room, use the Game Genie code DFCE-4BAD

Unused Flashing Palettes

All enemies that can give abilities periodically flash a golden version of their normal palette. Well, all enemies except Waddle Doo and Poppy Bros. Jr, though the palettes are in the game!

There are good reasons why these aren't used. Waddle Doo shares his palette with Waddle Dee, so every time he flashes his golden palette, Waddle Dee would too, and Waddle Dee has no ability. Likewise, there are variants of Poppy Bros Jr. that don't have any abilities, but they share their palette with Poppy Bros that do have abilities.
